Diagnostic criteria for 292.89 Hallucinogen Persisting Perception Disorder (Flashbacks)
(cautionary statement)
A. The reexperiencing, following cessation of use of a hallucinogen, of one or more of the perceptual
symptoms that were experienced while intoxicated
with the hallucinogen (e.g., geometric hallucinations, false perceptions of movement in the peripheral visual fields, flashes of color, intensified colors, trails of images of moving objects, positive afterimages, halos around objects,
macropsia, and micropsia).
B. The symptoms in Criterion A cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
C. The symptoms are not due to a general medical condition (e.g., anatomical lesions and infections of the brain, visual epilepsies) and are not better accounted for by another
mental disorder (e.g., Delirium,
Dementia, Schizophrenia) or hypnopompic
hallucinations.
